edit: Adding a bit more, the people being bubbled away will likely tend to just isolate. You might think you like that idea, but having spent some time in isolation, I will attest that it kind of messes with your head. You lose your "phase lock" with society on a lot of different norms, small and large. The stereotype of the "dangerous loner", though not always fair, attests to this reality.

If you want to keep someone as a useful member of society and not a tragedy-of-the-day, you have to keep talking to them.
